2 Claims.

This invention relates to the class of agricultural machinery-it is a trailer to be coupled to a farm tractor and filled in the field with chopped hay, chopped corn ensilage or other chopped: crops. and blown into this tractor by a suitable field harvester or other similar machine.

Referring to figures of the drawings accompanying and forming a part of this application:

Fig. 1 is a side view of the trailer with the wheels on the near side removed to show the underframe.

Fig. 2 is a top view of the trailer.

Fig. 3 is a front view of the trailer, the pow-er take-off and the tractor coupling devices being omitted.

Fig. 4 is a partial sectional view taken along 4-4 of Fig. 2.

Fig. 5 is a partial top view of Fig. 4, specifically to show the connection between the side angle irons and chain links.

Throughout the drawings and description the same number is used to refer to the same part.

In Figs. 1, 2 and 3 the trailer is shown mounted on wheels l and axles 2. The axles 2 rotate on bearings 3 which are secured to channel irons 4 and cross bed channel irons 5.

U-shaped channel iron frames, vertical channels 4 and cross bed channels 5 are best shown in Figs. 1 and 3. Frames 4 are welded to side chan nel irons 6, Figs. 1 and 3. A wood box frame 1 is built upon channels 6. Angle irons 8 are bolted to the box frame 1' and are welded to channel frames 5. Steel braces 9 are welded to channel frames 5 and to the bottom of channel frame 4, Figs. 1, 2 and 3. Knee braces l are welded to the cross bed channels and vertical channels 4, Figs. 1 and 3. Angle irons II are welded to the vertical channels 4, Figs. 1 and 3. A long tongue piece I2 is welded to angle irons II. Angle irons l3, Fig. 1, are welded to parts 4 and I2. Stiifener angle irons M, Fig. 1, are welded to part l2 and front channel support I5. stiffener bars I6 are welded to parts l5 and i2, Figs. 1, 2 and 3. A tractor coupling plate H is welded to part I2 and is provided with a hole I8 for a coupling pin not shown. The Wood box frame 1 has a front closure I9 which is bolted to part I by angle irons 20, Figs. 1, 2, and 3. Part I is provided with a rear vertical swinging gate 2|, Figs. 1, 2 and 4.

Angle irons 22, Fig. 4 are bolted to the several wood boards of gate 2|. Part 2| is free to rotate about a pipe 23 on hinges 55, Fig. 2. Part 23 is supported at its two ends by parts 24, Figs. 1, 2, 3 and 4. A steel catch bar 25, Figs. 1, 2, 3

The crops are harvested, chopped 2 and 4, also rotates about part 23 and is secured to the several boards of part 2,! by bolts. Part 25 rests against, any one of angle irons 2-5, Figs. 2 and 4, which may be in position. Parts 26 are welded to the links Z'LFigs. 4 and 5, 0f the endless chain belts 28, Fig. 2, which fit. on sprocket 29, Figs. 2, 3 and 4. Parts 23, slide in shallow grooves of the bed plate 3|, Figs. 2, 4 and 5. Shafts 32, Figs. 3 and 4, are supported by bearings 33, Figs. .1, 2 and 3. Part 3| is supported by angle irons 55 which are welded to part 6. a

Power is taken from the tractor, not shown, through shaft 34, Figs. 1 and 2, thence through the universal joint 35, shaft 36, universal joint 31, shaft 38 to sprocket 39, Figs. 1 and 2. The right end of shaft 38 is supported by the bearing 43, Figs. 1, 2, 3. The left end is supported by the front channel support l5. A chain belt 4| connects sprocket 39 and sprocket 42 which is mounted to shaft 43, Figs. 1, 2 and 3. Brackets 44, Figs. 1 and 2, support the shaft 43 at intermediate points. A worm 45 i secured to the left end of shaft 43 which is supported by brackets 46. The worm 45 meshes with a worm wheel 4'! which is secured to rear shaft 32, Figs. 1 and 2. A wear take up frame is provided by parts 48, 49 and 53. Parts 50 are Welded to the side channel irons 8. As mentioned above sprockets 29 are mounted on rear shaft 32 with the endless chain belt 28 meshing with sprockets 29. Intermediate supports for the endless chain belt 28 are provided by wheels 5|, Fig. 4, at 52, Fig. 4, and bearings 53, Fig. 2. A feed pipe 54, Figs. 1, 2 and 3, leads from the "Papec field harvester or similar machine to the wood box frame I.

Operation.-The field harvester is driven in the field along side of the trailer. Power is shut off from the tractor, not shown, to the shaft 34 bringing parts 35, 36, 3f, 33, 39, 40, 4|, 42, 43, 45, 41, 29 and 26 to rest, with the steel bar 25 resting against one of the angle irons 23. With these at rest, the tractor pulling the trailer and the tractor pulling the field harvester are started up and down the field harvesting, chopping or shredding. The chopped or shredded field crops are blown by the fan of the harvester through the pipe 54 into the wood box I. When the trailer is filled, the tractor pulls it to the silo.

Power is supplied from the tractor to the power take off shaft 34 setting in motion 35, 35, 31, 38, 33, 49, 4!, 42, 43, 45, 47, 29 and 26. As parts 26 move to the rear of the trailer it moves the load against the rear gate 2| and catch bar 25 and swinging the rear gate 2| outward the load is then dumped into a box.

Having now described this invention, we claim:

1. A tractor trailer comprisingin combination, a box body, said body having a continuous plate bottom, a wear take-up frame adjusting the taut of the said bottom said body provided with pivotal vertically arranged closures at the ends of the body, side chains provided with sprockets and axles carried by the said body, a power take ofi at the end of the said body constructed and arranged to take power from a tractor, the said power take off being provided with sprocket and chain connection devices whereby the said chains are operated, and the said side chains having spaced transverse angle irons arranged to sweep the said plate bottom of the said body and clear the said plate of chopped hay thereon, said body having supporting wheels and axles.

2. A tractor trailer comprising in combination a box body adapted to be moved about from place to place, said body having a continuous plate bottom, a wear'take-up frame for adjusting the taut of the said bottom said body being provided with movable closures at the ends, side chains provided with sprockets and axles carried by the said body, a power take off at the end of the said body constructed and arranged to take power from a tractor, the said power take oif being provided with sprocket and chain connection devices whereby the side chains are operated, and the said side chains having transverse angle irons connected therewith and arranged to sweep the said plate bottom of the said body when the side chains are operated and thereby clear the said body of chopped hay.
